ENewsletter widget appears broken


I purchased a one month subscription as I wanted to test a few plugins, as of now I only need this to work; eNewsletter plugin.

There is no guide explaining the installation and setting up ? That was a shocker. (or am I missing something?)
I have installed the plugin, added my SMTP details taken from gmail account, so far it doesn't work.. smtp error: failed to authenticate.

Second the widget is broken, and how do I add more fields to it ?
